Question

The diameter of a metallic ball is 4.2 cm. What is the mass of the ball, if the density of the metal is 8.9 g per cm³?

KnowledgeBoat · Accepted Answer

Given, The diameter of the metallic ball (d) = 4.2 cm Radius of the metallic ball (r) = cm = 2.1 cm The density of the metal = 8.9 g per cm³ We know that, Density = Mass = Density × Volume ...........(1) By formula, Volume of the metallic ball (V) = Substituting values we get : Substituting value in equation (1), we get : Mass of the metallic ball = 8.9 × 38.808 = 345.39 g Hence, the mass of the ball is 345.39 g.
